Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘LVDIP1816’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

An European Plant Breeder's Rights application for the instant plant was filed by the Inventor/Applicant on Jun. 7, 2021, application number 2021/1469. Foreign priority is not claimed to this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘LVDIP1816’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Vacaria, Brazil. The objective of the breeding program is to develop new strong and freely flowering Mandevilla plants with attractive flowers and good garden performance.

The new Mandevilla plant originated from a cross-pollination in 2017 in Vacaria, Brazil of Mandevilla hybrida ‘Fisrix Hopink’ (trade name, Rio Hot Pink), disclosed in U.S. Plant Pat. No. 20,672, as the female, or seed, parent with Mandevilla hybrida ‘Sunmandecrim’, disclosed in U.S. Plant Pat. No. 15,539, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Vacaria, Brazil in November, 2018.

Asexual reproduction of the new Mandevilla plant by terminal stein cuttings in a controlled environment in Vacaria, Brazil since January, 2019 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LVDIP1816’. These characteristics in combination distinguish ‘LVDIP1816’ as a new and distinct Mandevilla plant:

-   -   1. Upright to outwardly spreading and semi-trailing plant habit.     -   2. Moderately vigorous to vigorous growth habit.     -   3. Early and freely flowering habit.     -   4. Single bright red-colored flowers that resist fading.     -   5. Good container performance.

Plants of the new Mandevilla can be compared to plants of the female parent, ‘Fisrix Hopink’. Plants of the new Mandevilla differ primarily from plants of ‘Fisrix Hopink’ in the following characteristics:

-   -   1. Plants of the new Mandevilla have larger flowers than plants         of ‘Fisrix Hopink’.     -   2. Plants of the new Mandevilla have bright red-colored flowers         whereas plants of ‘Fisrix Hopink’ have rose red to cherry         red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent, ‘Sunmandecrim’. Plants of the new Mandevilla differ primarily from plants of ‘Sunmandecrim’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more upright than plants of         ‘Sunmandecrim’.     -   2. Plants of the new Mandevilla have lighter-colored flower         throats than plants of ‘Sunmandecrim’.     -   3. Flowers of plants of the new Mandevilla resist fading with         development whereas flowers of plants of ‘Sunmandecrim’ fade         with development.

Plants of the new Mandevilla can also be compared to plants of Mandevilla sanderi ‘Fisrix Dered’, disclosed in U.S. Plant Pat. No. 20,714. In side-by-side comparisons, plants of the new Mandevilla differ primarily from plants ‘Fisrix Dered’ in the following characteristics:

-   -   1. Plants of the new Mandevilla are more vigorous than plants of         ‘Fisrix Dered’.     -   2. Plants of the new Mandevilla have larger leaves than plants         of ‘Fisrix Dered’.     -   3. Plants of the new Mandevilla have bright red-colored flowers         whereas plants of ‘Fisrix Dered’ have more scarlet-colored         flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 10.5-cm containers in a polyethylene-covered greenhouse in Merano, Italy and under cultural practices typical of commercial Mandevilla production. During the production of the plants, day temperatures ranged from 20° C. to 28° C. and night temperatures ranged from 10° C. to 18° C. Plants were 20 weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
